Method Detail

values

public static TimeUtil[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (TimeUtil c : TimeUtil.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static TimeUtil valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

toTimePrecision

public static java.lang.String toTimePrecision(java.util.concurrent.TimeUnit t)

Convert from a TimeUnit to a influxDB timeunit String.

Parameters:

t - the TimeUnit

Returns:

the String representation.

toInfluxDBTimeFormat

public static java.lang.String toInfluxDBTimeFormat(long time)

convert a unix epoch time to timestamp used by influxdb. this can then be used in query expressions against influxdb's time column like so: influxDB.query(new Query("SELECT * FROM some_measurement WHERE time >= '" + toInfluxDBTimeFormat(timeStart) + "'", some_database)) influxdb time format example: 2016-10-31T06:52:20.020Z

Parameters:

time - timestamp to use, in unix epoch time

Returns:

influxdb compatible date-tome string

fromInfluxDBTimeFormat

public static long fromInfluxDBTimeFormat(java.lang.String time)

convert an influxdb timestamp used by influxdb to unix epoch time. influxdb time format example: 2016-10-31T06:52:20.020Z or 2016-10-31T06:52:20Z

Parameters:

time - timestamp to use, in influxdb datetime format

Returns:

time in unix epoch time
